SPECIFICATION forming part of Letters Patent No. 600,445, dated March 8, 1898.

Application filed October 5, 1897. Serial No. 654,152. (No model.)

T0 @ZZ whom, t may concern;

Be it known that LWHITFIELD Il. PIERsoN, a citizen of the United States, residing at Randolph, in the countyof Cedar and State of Nebraska, have invented a new and useful Egg-Tester, of which the following is a specitcation.

The invention relates to improvements in egg-testers.

The object ofthe presentinvention is to im- Yprove the construction of egg-testers and to provide a simple, inexpensive, and efficient device adapted for testing eggs either during the day or at night and capable when a lamp or other lighting device is employed of accurately throwing the light upon the eggs.

A further object of the invention is to provide a reiiector which will be capable of ready adjustment to position it properly with relation to the lamp employed, so that any size or kind of lamp may be used.

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of an egg-tester constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail sectional view illustrating the construction ofthe ways for the side bars of the support for the reflector.

Like numerals of reference designate corresponding parts in the several figures of the drawings.

1 designates a rectangular casing upon which is mounted a removable top or cover 2, provided at its front and side edges with a depending llange 3, formed by strips secured to the top or cover and engaging the body portion 1 of the casing. The casing receives an inclined mirror 4, extending from the bottoni of the front wall of the casing to the rear wall of the same, and this mirror is supported in position by a lower transverse cleat 5 and an upper peg G or other suitable fastening device. The cleat is arranged above the lower edge of the inclined mirror, and the fastening device 6, which is mounted upon the rear wall of the casing, is adapted to be removed to enable the reflector to be taken out, if desired.

The top or cover of the casing is provided with a series of elliptical egg-receiving openings 8, located above the inclined mirror. An inclined tube 9 is mounted ,upon the top or cover at the front end thereof to permit the operator to lookinto the interior of the casin g.

Sunlight is sufficient for testing eggs for consumption, but when it is desired to test. eggs at night or select them for hatching purposes a lamp 10 or other lighting device is employed and is supported upon a rearward extension of the top or cover. This rearward extension is supported by a bracket 1l, mounted upon the exterior of the rear wall of the casing and adapted to prevent the top or cover from tipping under the weight of a lamp.

The light from the lamp is thrown upon the eggs by means of an adjustable reflector 12, mounted in rear of the lamp upon a supporting-frame consisting of adjustable side bars and a connecting cross-piece or roll 14, which is provided at its ends with suitable journals arranged in perforations of the upper ends of the side bars 13. The roll or cross-piece is secured in any desiredadj ustment by a set-screw mounted upon one of the side bars 13 and engaging one of the journals 16.

The refiector 12 is provided with a shank 17, forming a pivot and permitting the reflector to be swung laterally to the right or left, while the roller or cross-bar permits it to be elevated or depressed to the desired extent.

The side bars 13 of the supporting-frame of the reflector are mounted .in suitable ways formed by inclined bars 18, secured to the outer faces of the casing and provided at their inner faces with longitudinal grooves 19. The reflector-supporting frame is secured at the desired adjustment by set-screws 20, mounted on the bars 18 and passing through perforations thereof and engaging the side bars 13. The side bars 13 are arranged in re- COVGI.

l'OO

flanges 3 are cut at an angle to correspond to the inclination of the reflectorsupporting frame.

The invention has the following advantages: The egg-tester is simple and comparatively inexpensive in construction and is capable of permitting eggs to be lrapidly examined. Eggs may be tested by sunlight or artificial light, and when a lamp is employed the reflector is capable of ready adjustment to correspond to the size of the lamp and to throw the light properly upon the eggs.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention, such as varying the number of the elliptical egg-receivin g openings of the top or cover and the like.

What I claim is- 1. An egg-tester comprisingacasinghaving a series of egg-receiving openings, a mirror arranged within the casing, a lighting device arranged at the exterior of the casing, and a reflector capable of moving bodily upwardly and downwardly and arranged to swing vertically and horizontally, whereby the reflector may be adjusted to throw the light in the proper direction, substantially as described.

2. An egg-tester,comprising a casing having a horizontal top with egg-receiving openings, a mirror arranged Within the casing, a lighting device arranged on the exterior of the casing, a supporting-frame adj ustablysecured to the casing and capable of upward and downward movement, and a reflector pivotally mounted on the supporting-frame, substantially as described.

3. An egg-tester comprisinga casing having a top provided with egg-receiving openings, a mirror arranged within the casing, a supporting-frame comprising side bars adjustably mounted on the casing, and a connecting cross-bar journaled on the side bars and capable of rotation, and a reflector having a pivot mounted on the cross-bar whereby the reflector is permitted a lateral adjustment, substantially as described.

4. An egg-tester comprisinga casing having a top with egg-receiving openings, inclined bars mounted on the exterior of the casing and having grooves forming ways, a supporting-frame composed of inclined side bars arranged in the said ways, and a connecting cross-bar journaled on the side bars, a reflector mounted on the cross-bar, and means for securing the side bars at any desired adjustment in the Ways, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

WHITFIELD I-I. PIERSON.
